Tb1 Bi2 Br1 O4
semiconductor· Tb1 Bi2 Br1 O4
Tb₁Bi₂Br₁O₄ is an experimentally synthesized mixed-metal halide oxide semiconductor combining terbium, bismuth, bromine, and oxygen. This rare-earth bismuth compound belongs to the family of layered halide perovskites and related structures, which are of significant research interest for optoelectronic and photonic applications due to their tunable bandgaps and potential for efficient light emission or detection. The material remains largely in the research phase; its practical utility depends on further development of synthesis methods and demonstration of performance advantages over established semiconductors in specific device contexts.
